Post #141,299 by deSitter 2/11/04 10:32:08 PM Reply	Re: blow me read the quoted man pages I cited!!! You misinterpreted the syntax of the page... You'll notice that it starts tar [-]{cvf...} This means, optional dash, then come any number of options. The tar options MUST come first, and they can be preceded by a dash or not. tar is one of the oldest things in UNIX. I'm almost certain that the funny option behavior is a consequence of the context you would find tar operating in - dumping and restoring files from tapes - and the dash was needed to allow tar to understand what kind of tape drive it was dealing with. A tar command from that day probably bore little resemblance to a standard UNIX command of today, and looked more like a TSO tape operation with explicit blocking and record layouts. -drl

Post #141,306 by deSitter 2/11/04 11:38:03 PM Reply	Re: also notice the description of the flags Just the dash is optional. Apparently original tar only had the non-dashed ganged options. The dashes were added for people aready afflicted with automatic switch prefix disease. See docs for gnu tar "Styles". -drl

Probably because the dash IS an option on its own, to tar? -NT - (CRConrad) - (16) - Feb. 11, 2004, 07:32:41 PM EST

No, for many (most?) old commands, that's DOUBLE dash. (*) - (CRConrad) - (14) - Feb. 11, 2004, 07:57:44 PM EST
